MDL Marinas expands storage capacity at Shamrock Quay

Marking a significant expansion of its renowned Shamrock Quay marina in Southampton, MDL Marinas has confirmed its recent acquisition of the 3.2-acre plot at Lower William Street is to be utilised for additional boat storage, manufacturing and boat sales.

The acquired site, strategically located adjacent to the marina, provides much-needed space to accommodate the growing demand for secure boat storage. The expanded storage area has been enhanced with additional CCTV cameras, as well as new power and water outlets, offering improved security and convenience for boat owners.

Shamrock Quay, known for its vibrant community and excellent facilities, now offers boat owners greater convenience and flexibility, particularly during the winter months when secure storage is in high demand.

In addition to expanding storage, the new site – designated as Millstone Point – incorporates a vast building with offices, which MDL plans to rent out to potential tenants looking for prime office space within a marina setting.

Encompassing prime waterfront and deep-water access, an upgraded pontoon has also been installed at Millstone Point which can now accommodate yachts up to 50 metres in length, making this an ideal base for visiting superyachts and other large vessels.

Recent upgrades at Shamrock Quay

In addition to the new storage capabilities, MDL has invested in a series of enhancements at its Shamrock Quay marina to improve the overall customer experience.

Recent upgrades include:

  • Pontoon replacement: A complete overhaul of H to K pontoons, ensuring modern and safe mooring facilities.
  • New pontoon access gate: A secure and user-friendly entrance gate for H & K pontoons, providing easy access for berth holders.
  • Road resurfacing: Key areas of the marina have undergone road resurfacing, improving traffic flow and access.
  • Lower-level car park surfacing: The lower-level car park has been resurfaced to provide better parking facilities.

Exclusive winter offers

To complement its expansion, MDL Marinas has launched a raft of exclusive winter offers at Shamrock Quay, offering boat owners excellent quality and great value berthing, lifting and storage packages.

Running from 1 October 2024 to 31 March 2025, visitors and berth holders can benefit from discounts on berthing and boatyard services, with savings of up to 40 per cent on winter berthing and up to 45 per cent on maintenance services, including lifting, scrubbing and relaunching.

These offers are available not only at Shamrock Quay but also at other prime MDL locations, including Hythe Marina Village, Ocean Village and Port Hamble Marina. MDL’s riverside marinas, such as Penton Hook on the River Thames and Chatham Maritime Marina on the River Medway, are also offering discounted winter berthing packages.

With prices starting at just £112.50 per metre for three-months’ winter berthing, and savings of up to £700 on boatyard services, these offers provide an excellent opportunity for boat owners to extend their boating season and ensure their vessels are well-maintained throughout the winter.

Tim Mayer, MDL’s Sales & Marketing Director, said: “Our acquisition of land adjacent to Shamrock Quay earlier this year and the ongoing improvements demonstrate MDL’s dedication to expanding our offering and providing the best facilities for boat owners. 

“We’re thrilled to support our customers with enhanced storage solutions and fantastic winter offers, not just at Shamrock Quay but across several of our premium marinas. Whether you’re looking for a secure winter mooring or need to carry out essential maintenance, our offers provide great value for money.”
